1. N-Phenylmaleimide irreversibly inhibits pyruvate transport into rat heart and liver mitochondria to a much greater extent than does N-ethylmaleimide, iodoacetate or bromopyruvate. alpha-Cyanocinnamate protects the pyruvate transporter from attack by this thiol-blocking reagent. 2. In both heart and liver mitochondria alpha-cyanocinnamate diminishes labelling by [3H]N-phenylmaleimide of a mem...

During the past decade, Endovenous Laser Ablation (EVLA) has been introduced as a minimally invasive alternative to high ligation and open surgical stripping of the incompetent Great Saphenous Vein (GSV) or Short Saphenous Vein (SSV). There is great variability in EVLA protocols and at the present time there is data from more than 60 publications with more than 15000 EVLA treatments reporting g...

The EFAR collaboration has measured the structural parameters (half-luminosity radii, total magnitudes, central velocity dispersions and Mg indexes) of galaxies in 84 clusters of the Hercules-Corona Borealis and Pisces-Cetus regions, with redshifts 6000< cz <15000. Analysing this database by means of a Maximum Likelihood algorithm, the Fundamental Plane relation derived is in agreement with exi...

An analytical method based on solid phase extraction has been developed and validated for analysis of amoxicillin in human plasma using gemifloxacin as an internal standard. A COSMOSIL 5C18-PAQ column provided chromatographic separation of analytes followed by detection with mass spectrometry. The method involves simple isocratic chromatographic conditions and mass spectrometric detection in th...

Medium-resolution (R ≃ 15000) circular spectropolarimetry of T Tauri is presented. The star was observed twice: on November 11, 1996 and January 22, 2002. Weak circular polarization has been found in photospheric absorption lines, indicating a mean surface longitudinal magnetic field B‖ of 160±40 G and 140±50 G at the epoch of the first and second observations respectively. While these values a...

An application of the Viola and Jones object detector to the problem of aircraft detection is presented. This approach is based on machine learning rather than morphological filtering which was mainly used in previous works. Aircraft detection using computer vision methods is a challenging problem since target aircraft can vary from subpixels to a few pixels in size and the background can be he...

Approximately 60% of all households in the United States have a pet, with about 74.8 million owning a dog and 25% having two dogs. There are approximately 88.3 million cat owners in the USA, with 56% of them having more than one cat (1). While the bond with animals for companionship goes back 10 000 – 15000 years, domestic pets are also capable of transmitting diseases and causing injury. Zoono...

A conversion from orthographic (written) form to a phonetic transcription is the first stage in a text-to-speech system. In this study, algorithms are presented to facilitate the text-to-phoneme (TTP) conversion for the Farsi language. Using a lexicon of about 15000 base morphemes, word formation rules are investigated and implemented. Moreover, a word segmentation of the written sentence has t...
